This thesis is a study of what is said to be at issue in the nuclear weapons debate and constitutes the beginning of an attempt to understand its nature and significance . The technique adopted has been to offer an initial presentation of rival rationales in order to introduce the main concepts and show something of the force of these developed, positions (Vol I pp 7-30) . The two rationales are then related point by point , to give the analytical framework used in the subsequent interviews (pp 31-9) . Each pair of points is expanded and commented upon , and detailed references are given to the books and articles from which the analysis was drawn (pp 40-214) . The next section relates all of this briefly to the main party platforms in Britain , as of June 1987 (pp Zt 1- zt ) Volume II is made up of complete sets of responses to the framework of questions generated in the earlier chapters . The advantages of this method are i that in each case the rationale is laid out verbatim 9 so that premises are explicitly stated and the dependence of subsequent upon prior arguments is clearly seen . This in itself is very rarely done which is why so many proposed policies are so often , and so widely misunderstood . that , because all those consulted have responded to the same set of questions , their alternative sets of answers can be compared with one another point by point . This is the crucial and unique advantage of the approach adopted here . It ensures that what is at issue can be precisely pinpointed. The results as recorded here are in themselves striking and illuminating More important still they open the door to detailed future investigation of a kind which can be done in no other way.
